“…It is widely reported that a large number of earth embankments or slopes were damaged during the past great earthquakes (Omer and Resat 2002;Bakir and Akis 2005;Singh et al 2005;Kamai and Sangawa 2011;Toyohiko et al 2011;Huang et al 2012aHuang et al , 2013. In 2008, about 197,481 slope failures were triggered by Wenchuan earthquake of China (M w 7.9 or M s 8.0) Xu et al 2014c), and the phenomena of seismic liquefaction and subsidence were also observed (Huang and Jiang 2010;Huang et al 2011Huang et al , 2012b.…”

In order to study the seismic response of the embankment slopes with different reinforcing measures, shaking table tests were performed on three embankment slope models (i.e., unreinforced embankment slope, 2-layer reinforced embankment slope and 4-layer reinforced embankment slope). Wenchuan earthquake motions and white noise excitations were performed to investigate the change of the model parameters, the horizontal acceleration response, the vertical acceleration response and the dynamic earth pressure response of embankment slopes. A comparison was made on the seismic response among the embankment slopes with different reinforcing measures. The results show that the natural frequency of reinforced embankment slope is larger than that of unreinforced embankment slope, and the reinforced embankment slope is less sensitive to seismic excitation. Horizontal acceleration response is obviously amplified by embankment slope. Horizontal acceleration magnification presents a decreasing trend with the increase of the peak value of input horizontal acceleration, and the decreasing ratio is higher for reinforced embankment slope. The vertical acceleration magnification of reinforced embankment slope is much smaller than that of unreinforced embankment slope, and the nonlinear characteristic of embankment slope in vertical direction is not as obvious as that in horizontal direction. Residual earth pressure is mainly induced at the upper part of embankment slope.
